Spring Boot Web 项目设置Eclipse

Question

I am new to Spring Web development. Basically, I need to know how to run the Spring project in Eclipse IDE. Here are the detailed steps I have perfoormed so far, with pics/code to support my question.

1. I visited Spring Initializr site and downloaded a maven project folder. I endered the following information: Project: Maven Project Language: Java Spring Boot: 3.0.0 (SNAPSHOT) ProjectMetadata - Group: com.example ProjectMetadata - Artifact: demo10 ProjectMetadata - Name: SpringTest Dependencies:
   Spring Web - Build web, including RESTful, applications using Spring MVC. Uses Apache Tomcat as the default embedded container.

2. I imported the downloaded file into Eclipse as Existing Maven Project. (Eclipse Version 2021-12(4.22.0)

3. Created the following class was created by spring initializer

package com.example.demo10;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class SpringTestApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringTestApplication.class, args);
    }

}

4. I created the following controller class

package com.example.demo10;


import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;


@RestController
public  class MyController {
    @GetMapping("/welcome")
    public String getWelcome() {
        System.out.println("test");
        return "we are fome";
    }
}

5. Here is the project file structure in Eclipse

6. Here is the pom file

<?xml version="1.0" encoding="UTF-8"?>

            </releases>
        </pluginRepository>
    </pluginRepositories>

</project>

So following are my two questions: a. From this point how do I run the project on Tomcat server. I already have two versions of Tomcat installed. b. What is the url I should use to call the api?

Thanks

Answer 1

as you said, Uses Apache Tomcat as the default embedded container. you can run your project when you identify @SpringBootApplication annotation in your main class

Spring boot use url that is localhost::8080 as a default.Also, you can change it using application properties files for example "server.port = 9999" and your url will be localhost::9999
